Dallas and Oak Cliff have decided to get together on plans for a streetcar. Previously, Oak Cliff and Fort Worth were going to go in together to seek TIGER stimulus funding for new streetcar projects. However Dallas has plans for a streetcar as well, so bringing the ideas together is smart, considering it will lower the overall costs of a system that would likely run just blocks away from the other if allowed to plan separately.
I'm going to take a wild guess and venture to say that they won't get funding for the project. Given the whole country is foaming at the mouth for only $1.5 billion dollars in funds, it would be hard to expect projects like these to get funding over those more established. The low funding with so much interest makes that extra $2 billion from cash for clunkers look silly as well, considering there are transit projects that could help guide new growth that reduces VMT versus paying for people's new cars so they can drive more.
